摘要
Endodontic-periodontal lesions are characterized by the involvement of the pulp and periodontal disease in the same tooth. Despite successful root canal treatment, if the majority of bone support has been lost from periodontitis, the tooth may have a poor prognosis. In severe endodontic-periodontal lesions, the periodontal tissue regenerates poorly because of the significant loss of the periodontal ligament and cementum, poor tooth stability, and bone defect morphology unfavorable for bone regeneration. To overcome these difficult situations, in this case, osteotomy of the replantation bed and tooth replantation with horizontal rotation and deep placement were performed. To improve periodontal regeneration, fibroblast growth factor (FGF) 2 was applied to the artificially made periodontal defect. In addition, orthodontic extrusion of the deeply replaced tooth was performed for potential coronal migration of the periodontal tissue. This case presents a unique multidisciplinary method of treating severe endodontic-periodontal lesions using intentional replantation combined with FGF 2 application and orthodontic extrusion.
